all i can say it keep it simple...i never had a problem using the recommended oil going on three years using BOTH my cheap little yong hengs.matter of fact after three years of pumping air they have not let me down nor have run times increased...use them for what they were designed to do and there will be no problems.when the air pressure gets up around 2500 psi the yong heng really smooths out and jumps right up to 3300 psi with no strain at all.fill time from 145 bar to 225 bar is around 50 seconds and temp to 41c.
Yong Heng buying ALERT ! these guys appear to have them back in stock on ebay again , and they excepted my offer of $ 250 on the 1 I bought ...good luck ! ,and thank me very much LOL !

I didn't get it at the initial offer, but I got it for a little less than asking. Enough to cover taxes.Maybe could have found one for less eventually, but trying out my new hand pump made me realize my body isn't 19 anymore.I also have a SCBA tank coming in. I'll have that one hydro tested at a dive shop just to make sure it's safe, then I'm good for an air supply.

You will be so glad you invested in this charge equipment ,so you can enjoy your shooting ..

You will be so glad you invested in this charge equipment ,so you can enjoy your shooting ..Thank you for the kind words. The only challenge that remains is to source a good compressor oil. How many quarts/liters does it take? A quick google search shows a lot of 5 gallon buckets of oil, but I just want to get the first fill right now.
I just bought a half gallon of Chemlube 751 here for 63.00 shipped. ($36 for the oil, $23.35 shipping & $3.65 in tax) off eBay. Ordered Monday and will be here today. Shipped by ProTec Air Systems out of Corpus Christi, TX.Here's a link to it: https://www.ebay.com/itm/222243983468Not sure if it was a good deal but I wanted to go with what the guys here who are much smarter than me suggested.I just got my Yong Heng pump just before Christmas (used, NEW) from a guy that got it as a gift and knew nothing about it or the gun he got. He didn't want it and sold it to me. It had oil already in it and I used it about 1 1/2 to 2 hours and the oil was turning dark and it was starting to give off a burnt oil smell. Shut it off and drained it and will refill it today and run it for a short time and probably drain and refill again to make sure all the old stuff is out.Thanks Guys, Mark
I wonder how good this is:It's Royal Purple compressor lube, so it's not like running motor oil.
